HORMIDAS JARRY, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR TO THE WHITIN NEACHINE WORKS, OF WHITINSVILLE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

To all whom it may concern:

Be it known that I, HoRMmAs JARRY, a citizen ofthe United States,'residing in Lawrence, in the county of Essex, State of Massachusetts, have invented the following described'new and useful Improvements in *l eilmann Combers.

The invention is an improvement in construction of the said type of combers with the view of providing better facility for access to, and greater clearance beneath and around the journaled ends of the piecing or detaching rolls thereof and seeks also to reduce the number of places around such parts where dirt and lint can collect, and otherwise aims to simplify and improve the said type of machines.

By reason of the necessary compactness of the operating parts of the piecing and detaching mechanism it has heretofore been a. matter requiring much diligence and attention to keep the surplus oil and dirt collecting on and around the roll-journals from working onto the faces of the rolls, where it soils the product. In providing means for alleviating this objection, the present invention, is more particularly an improvement on the invention disclosed in my application filed February 27, 1911, Serial No. 611,118, addressed to the remedy of the same defects, and involves improved methods of supporting the front casing and sliver pan in their proper relation to the rest of the mechanism whereby certain diliicultly constructed parts of the former application are eliminated and certain other simplifications are made available, as will more fully appear in the description below and the drawings forming part hereof.

In the drawings Figure 1 is a vertical transverse section through one of the combing heads of a .Heilmann comber embodying the improvements of this invention, the section being taken through the central or working portion of the head as will be apparent to those skilled in. this art. Fig. 2 is an enlarged section of certain of the parts shown in Fig. 1, being taken on section line fl-II of Fig. 3, which latter figure is a front elevation on the same scale as Fig. 2 showing the parts shown therein and illus trating the symmetrical nature of the new construction as applied to the uprights between the combing heads. Fig. 1 is a top Specification of Letters Patent.

plan of the pillow of the plumber block showing the pillow cap in perspective at one side. Fig. 5 is a separated detail of the casing attachment device, and Fig. 6 is a cross section of the sliver pan seating means.

It will be understood by those versed in this subject that the comber frame comprises a main horizontal girder 1 (Fig. 1) extending the full length of the machine and upon which the series of upright frame standards 2 is mounted. These standards form the end and intermediate frame supports of the several combing heads of the comber, but only one of them appears in the drawings because they are all alike. The standards 2 may be made of any usual or suitable shape to support the lap-feeding devices, the combing mechanism and the other usual parts so that they will operate according to the wellknown Heilmann principle, which need not be here described. These parts appear in their usual arrangement in Fig. 1 and it will be understood that they properly cooperate to comb the staple in separate tufts or detachments which are successively overlapped by the piecing mechanism and by it formed into a continuous sliver, which passes thence into the sliver pan 3, through its condensing trumpet 3 and the calendar-rolls 4 to the apron 5. The piecing mechanism comprises a lower piecing roll 7, an upper piecing or detaching roll 8, usually leather-covered, and an upper fluted piecing roll 9, usually of brass and mounted in the pivoted horsetails as later explained. The lower roll is formed on, or as a part of, a horizontal shaft common to all the combing heads and is driven from the drive-head of the machine at one end, while the two upper rolls are individual to each combing head and are driven in whole or in part by their contact with the lower roll. By reason of the nature of their support these rolls 8 and 9 are normally removable while the other roll, being part of the longitudinal shaft above referred to is normally fixed in position. The mounting of the shaft of the lower piecing roll is formed by a set of plumber blocks mounted on the inclined top margins of the several frame standards 2, each block comprising a base member or pillow 11, such as shown more clearly by Fig. 4, and a pillow cap 12 also appearing in that figure. The pillow is provided with an oblong slot 13 to receive a bolt 14 by means of which it is secured to the top of the standard and upon which it is therefore adjustable toward and from the journal 6 of the combing cylinder shaft. The journal seat 15, formed thereon for the lower piecing roll shaft 7, is located at the rearward end of the block, as also clearly shown in Fig. 4. The cap piece 12 is adapted to be held in place on the pillow and over the journal seat 15 by means of a suitably mortised joint and a bolt 16. At its rearward end the pillow block is also provided with a pair of bracket arms 17 which spring from the sides of the block below the journal seat 15 and extend rearwardly, and also slightly upwardly therefrom, to form the support for the bearing blocks 18 (Fig; 2) upon which the gudgeons of the piecing detaching roll 8 are adapted to rest. One of these gudgeons appears in dotted lines in Fig. 2, where it is marked 8 and the ends of such gudgeons (of two adjacent combing heads) also appear in the upper portion of Fig. 3, where they are similarly marked.

It will be understood that the pillows in= tended for use on the frame standards at the ends of the machine are, of course, provided with bracket arms 17 on one side only but for the intermediate standards, the pillows have such arms on both sides as in the case illustrated in Fig. 4. The bearing blocks 18 are inclined as shown and, for purposes of adjustment, each is provided with two screws arranged as shown in the drawings or in any suitable way to enable its position to be shifted with respect to the combing cylinder and the other rolls. A pair of stirrups 19 applied upon the gudgeon 8 at each end of the roll 8 serves to press it against the lower piecing roll 7 and toward the combing cylinder. The stirrups extend upwardly from their respective gudgeons and thence downwardly, passing the side of the pillow block just in front of the bracket arms 17 to a lower point where they are hooked to the weighted or sprin pulled levers 20. The latter are pivoted to the frame standards at the points marked 21. The springs for the levers are marked 20.

At a point toward its forward end and in front of the stirrups 19 the pillow block is drilled with two holes which represent the points of attachment thereto of the bases 22 of the pivoted horse-tails 24, on which the upper fluted rolls 9 are journaled. These horse-tail bases are made in pairs of 7/ rights and lefts and the end surface of each base is formed with a depending liner lip and is suitably machined so as to adapt it to fit truly upon the top surface and corner of the pillow and so as to be adjustable thereon in a direction parallel with the plane of the frame standard. For this purpose the base is provided with an oblong bolt slot through which its holding bolt 23 is inserted, the said bolt being screwed into the bolt hole in the pillow above mentioned. From its point of attachment to the pillow each horse-tail base extends, like a bracket arm, first laterally away from the block and then turns at about a right angle and eX- tends rearwardly toward the piercing rolls, reaching past the stirrup 19, and forming a space for the latter between arms 17 and 22 and the side of the pillow. At its rearmost extremity the horse-tail base turns upwardly in the form of a fork to carry the pivot of the horse-tail 24. The latter, which may be of any suitable type, is formed to receive the gudgeons of the upper fluted piecing roll 9 and also the clearer cover 26 thereof (Fig. 1) and is further adapted to hold the said piecing roll so that it will normally rest upon the top of the lower roll as indicated in the drawing, and so that the said roll can also be removed from this position by swinging the horse tails upwardly and backwardly in the usual manner. The horsetail base 22 also carries and includes the spring-pressed plunger 25 which acts upon the horse-tail sector to maintain the roll either in pressing engagement with the lower roll .or in its uplifted position, as the case may be and as will also be readily understood. It will be observed that the mounting of the horse-tail base as above described provides ample space beneath it and above the stirrup lever 20 to afford access to the latter and, also, when the stirrup has been unhooked, to the front side of the combing shaft bearing 6 The front casing 27 which closes in and protects the front of the combing cylinder 6 and its rotary brush 28, and other parts of the dotting system not shown in the drawings, is secured at its lower end to the side of the girder 1 by means of a suitable bolt, as shown, or other suitable form of attachment. At its upper end it is supported by an adjustable holder upon a rod 29, which spans the combing space between two of the upright frame standards. This rod may, if desired, be a fixed rod having no other purpose than to support the casing 27 but it is preferably adapted to serve also other purposes, as, for example, to relieve the weight or pressure on the stirrup levers or to turn the power on and off, in either of which cases it is made as a continuous rod or shaft running the full length of the machine and journaled in the intermediate frame standards. Whether fixed or movable, this rod or shaft 29 is mounted at such a level below the level of the piecing mechanism as not to obstruct access to the under side of the latter, and the means whereby it is connected to support the front casing is also set in a corresponding lowdown position. As indicated in the drawings, it will be seen that there is sufficient space above the rod and below the piecing mechanism in which the operator can insert his hand when necessary.

The attachment of the casing to the rod is formed by a hook-shaped arm 30 adjustably bolted to a bracket base 81, the latter being soldered or otherwise secured to the front of thecasing at a point well within the vertical edges thereof. The hooked-arm seats over the rod 29 and has a keeper 32 to hold it in that position without liability of displacement when the rod itself is moved or rotated in its bearings. The several parts of the attachment for the casing are shown separated in Fig. 5 where an ordinary linch pin is also shown for fastening the keeper to the hook. The casing is preferably pro vided with two attachment devices such as just described, and which are symmetrically disposed thereon as indicated by Fig. 2, but at some distance from the vertical margins of the casing. The latter is thus held rigidly in position and is thereby available to support the sliver pan, an additional function not heretofore assigned to the front casing, and one that promotes greatly the objects of this invention first above referred to in as much as the sliver pan can be thereby supported without the aid of members extending laterally from'the frame standards or downwardly from parts above. The upper margin of the casing may serve as formerly to support the flexible clearer blade that cleans the lower piecing roll 7, and when such a clearer blade is employed, the means to support the sliver pan may be mounted in front of it and indeed may as sist in holding it in place, if desired. The construction of the upper portion of this casing is shown more clearlyin the section view of Fig. 6 wherein it will be observed that the sliver pan seat consists of a short strip of metal 34 soldered or otherwise fastened to the face of the casing and extends forwardly and upwardly therefrom, terminating preferably in a rounded bead or rim.

In the case illustrated as well as in the ordinary Heilmann comber the sliver pan forms a part of an electric stop-motion circuit and for this purpose requires to be so mounted that it will normally maintain it self in a position out of contact with the upper calendar roll t, which forms the other terminal of the circuit. WVhen the sliver jams in the condensing trumpet 3 the pan is thereby drawn forwardly until the nose of the trumpet encounters the roll and thus closes the circuit, but in normal running the sliver pan should encounter suiiicient resistance to forward movement to prevent its accidental operation in this manner. In the present case such normal resistance is provided by the downwardly turned lip 37 at the rear of the pan, which laps over and rests on the pan seat 3 L engaging the latter in a plane of contact represented generally by the upper surface of the pan seat and which is so inclined that the gravity of the pan itself tends to cause it to assume and maintain its rearward position under normal conditons of sliver tension, but allows it to ride forwardly and upwardly against gravity when the sliver tension on the trumpet becomes abnormal. It will be understood that the pan seat is formed of such extent of forward projection as to meet this condition, and cooperate accordingly. The nature of the support, however, that is provided by the pan seat, is such that it is not necessary for it to extend horizontally the full width of the pan and it is consequently terminated at a point several inches remote from the intermediate frame standard, as indicated more clearly in the left hand side of Fig. 3, from which arrangement it will be observed that the entire mechanism for supporting the sliver pan is separate from the region around the roll journals. The sliver pan adjustment means also are isolated from this region, such means being the hooked arm devices 30 and 31 above described.

Adjustment of the sliver pan, toward and from the calendar rolls as well as in a vertical direction may be accomplished by ad justing the front casing 27 forward or back by the appropriate manipulation of the bolt 38 that holds the hook 30 on the base-bracket 31. By releasing the other connection of the casing to the frame, the casing and hence the pan seat, may be raised or lowered without shifting it laterally. \Vhen the rod 29 is employed as a means for relieving the pressure on the stirrup levers 20 it is provided with a suitable cam fast thereon, as indicated by the dotted line 39 in Fig. 2 so that by the rotation of the shaft the levers 20 may be lifted and the pressure thereby relieved from the stirrups and the detaching rolls 8.
